3286549 - Tax condition's exchange rate is incorrect

Certain tax condition's exchange rate is not correct in purchasing document.

This you can observe at pricing condition and at tax condition types too. 
So certain date's valid conversation rate not taken from OB08 but 1:1 rate used which is wrong.

So for example at Purchase Order if you go to invoice item tab, and press taxes button, and check a tax condition's details, then you see for example 1-1 exchange rate between two currencies like:
Currency        INR      Exchange Rate    1,00000
Doc. Currency   USD      Exchange Rate    1,00000         Local Currency  INR

Similar problem you might see at condition item tab's any pricing condition type's details.
